blackCanny Edges.
Following [1]}, we set \(\sigma =2\)  as Gaussian blur coefficient for the \(256\times 256\)  canny detection.
Canny edge priors \({\mathbf {\tilde{P}}_{ce}}\)  are optimized with Binary Cross-Entropy (BCE) loss in TSR. We use the mask-predict [2]} trick and sigmoid temperature parameters for better canny edge predictions, detailed in our supplementary.
